The league would begin to supplant baseball as America's most popular spectator sport in 1958, when the then-NFL Championship Game between the Colts and the [[New York Giants]] was broadcast nationwide (though ironically not in New York City) and ended in a sudden-death overtime win by the Colts.
==Arrangementand League Play==
The league is composed of 32 professional [[American Football|football]] teams from the [[United States]] (of the four major professional sports leagues it is the only one not to have a team located in [[Canada]]), divided into two conferences (the American and the National), each of which have four, four-team divisions. Although the divisions have "directional" names (East, North, South, and West) they have little meaning geographically (for example, the NFC East is comprised of the New York Giants, Philadelphia, Washington and Dallas, notwithstanding that Carolina is further east and geographically closer than Dallas to the other three teams) and much to do with rivalry and media (the aforementioned NFC East comprises four top-10 media markets, and all four teams have long-standing historic rivalries with each other; Dallas-Washington being the most well-known).
